i have 3.73's and drive like an old lady and get 10-11mpg empty even on the freeway...Maxtor said:I do not know what you guys are doing to get 13-15 mpg, but I have never got less then 17.8 mpg empty. Most of the time it is 18.2 to 18.8 mpg. I have two friends that have stock Dodge trucks, and they both get 20 to 22 mpg empty. I agree with Bartman that said that overall Ford trucks are by far the best out there. So what if a six cylinder gets a little better mileage than we do. I would not change to a Dodge just for better mileage. Don't drag race from a stop light, and keep the rpm's around 1950 to 2000 and your mileage should get a lot better. If you have a differential of around 3.73 and not 4.11 your mileage should be around 18 mpg empty.
